    The tune from Miller is for 19# Bosch type 3 injectors that's why I'm running them.

    Got the repaired maf and a new tune. runs better then before it seems but still rich about 7mpg.

    I pulled out my injectors and checked the resistance again all very close to 16 ohms, toggled the fuel pump for about 30 seconds and nothing is leaking. Replaced my coolant temp sensor just for the hell of it and I check for continuity through the ignition harness again. Now I'm stumped.

      A quick thought, could a bad valve adjustment cause a miss that I cant hear because of the cam and that cause the richness?

      How often do non oem CPS not work and cause misfires?

      got a crappy cell phone video.
